IMPROVEMENT IN ADJUSTABLE CATCHES FOR LATCHES.

Specification forming part of Letters Patent No. 148,662, dated March17, 1874 application filed I August 9, 1873.

To all whom it may concern:

Be it known that I, GEORGE W. BURR, of East Line, in the county ofSaratoga and State of New York, have invented a new and ImprovedLatch-Oatch, of which the following is a specification:

In the accompanying drawing, Fig. 1 represents a front View, Fig. 2 is aside view, and Fig. 3 is a horizontal section, of my improvedlatch-catch on the line 0 c, Fig. 2.

Similar letters of reference indicate corresponding parts.

My invention is an improvement in the class of catches for door and gatelatches, which are made vertically adjustable to accommodate the variouspositions the door or gate may assume in consequence of shrinkage,swellings, or other cause. The invention consists in combining aT-shaped catch with a slotted holder or guard plate, which is secured tothe gatepost by screws, so that by means thereof, the catch may beclamped and held by friction at any desired point, as hereinafter morefully set forth.

In the drawing, A represents the post or casing of the gate, door, orwindow, or other object to which the holder B is firmly attached by topand bottom screws (0. The middle part of holder B, between the endsthrough which the screws a pass, is raised to such a distance from postA that the base of catch 0 may slide below the same when the lower screw00 is loosened, but is rigidly held thereon when the same is tightened.A central vertical slot, 1), of holder B, guides the projecting part ofcatch 0, which is placed centrally and under right angles to its base.This projecting part is recessed for locking the latch therein, androunded off at its outer part in the usual manner, as shown in Fig. 2.

Y'Vhenever the position of the gate, door, or window has changed by theinfluences of the weather, shrinkage, or other cause, the catch 0 isvertically adjusted in holder B to correspond with the new position ofthe gate, forming thereby a very convenient attachment for the purpose.

I am aware it is not new to combine a catch and slotted guard plate orholder, and, therefore, disclaim such invention, and restrict myself tothe following claim:

The T-shaped catch 0 and slotted holder B, combined and constructedrelatively, as shown and described, so that the former may be clampedand held by friction between the post A and said holder, by means of thescrews a, in the manner specified.
